TWO-IN-ONE CHISEL Filed 001:. I, 19250 San/ey Pen/wilg@ ATTORNEYPatented Sept. 13, 1932 UNITED STATES miese PATENT OFFICE STANLEYrnNxosnr, or New Yoan, N. Y. i l* TWO-IN-ONE CHISEL Application lcd.October 1, 1930. Serial No. 485,741.

The object of this vinvention is the provi-l sion of a chiseling toolthat comprises a member provided with two cutting bits and which isdesigned for easily and expeditiously per- 5 forming a number offunctions, such for instance, as the longitudinal splitting of cordwood, the grooving of timbers along scribed lines or the notching ofsolid newel posts that receive in the said notches the lower step of lea stairway and which tool is characterized hy simplicity in constructionand reliability.

To the'attainment of the foregoing the invention consists intheimprovement hereinafterdescribed and definitely claimed.

in the drawing:

Figure l is an elevation of a tool employed for splitting cord wood.

the tool per se.

Figure 3 is a similar view but illustrating a slight modification. y

Figure 4 is an end view looking toward one of the bits.

My improved chiseling tool is constructed of a single piece of hardsteel or like material and includes two spaced Shanks 1--1 that aresharpened on one or on both of their faces to provide the outer'edgesthereof with bits 2. The shanks 1 merge into inwardly inclined arms 3,and the said arms, at their connected portions have aA central extensionin the nature of a head 4. By reference to the drawing' it will benoted'that vthe arms 3, have their outer faces, at the juncture with theshanks 1 substantially flattened, .as at 5, providing shoulders, whilein Figure 3 the Shanks 5 are extended or projected a suitable distanceabove the arms 3 to provide shoulders 6 that are spaced away from the 40the tool is to be made in di'erent sizes and that the Shanks 1 may bearranged close together or spread a material distance apart. Also it isto he understood that the tool, ex cept for the sharpened bit portions 2may ,describe y arms. It is, of course, to be understood vthat be roundor s uare in plan and when the tool is employed or splitting logs asdisclosed by Figure l of the drawing the Shanks 1 have their oppositefaces beveled to points toprovide the bit disclosed by the full lines inFig-v ure 4,- of the drawing. The tool?. when partly forced into the logby the impact of the force of a sledge or the like willcause the log tosplit into slats in an easy and expeditious manner. The shoulders 5 or 6providegja means whereby the hammer may be directed against either ofthe Shanks and consequently either of the bits.

It will be readily noted that the spaced bits, can be readily arrangedupon a scribed line and that a timber may be rooved or split along suchline. After the bit has been Figure 2 is an enlarged side elevation of`forced into the timber for a determined distance and a groove in thetimber is desired one of the bits may be forced longitudinally throughthe slots or openings made by thel pair of bits through the impact offorce delivered against the shoulder and the shank therefor so that thecut wood can be thus forced out to produce the complete groove. The toolis also especially desirable for use in notching the corners of solidnewel osts, which with the ordinary construction o chisels involves alaborious task on the part of the carpenter, as the two bits cuttingalong the and quickly remove the corner of the newel sts. f While I haveherein illustrated a satisfactory embodiment of my improvement myfeatures of invention are capable of extended application and I do notwish to be limited to the s ecic structure herein shown and f .Havingdescribed the invention, I claim: A wood working and splitting toolcomprising a pair of s aced parallel Shanks having wedge-shaped cuttingedgesr and provided at their upper ends with impact surfaces parallelwith said scribing linesv on the newel posts will easily ower endsterminating in cutting edges, there being r"inclined arms springing fromthe upper inner side portions of said Shanks and inclined at equalangles with relation to each other, said arms merging with each other attheir u per ends and merging with an upstanding lliead portion,^saidhead portion being midway between the Shanks and parallel thereto, andprovided at its upper end with an impact suree lying parallel with allof the cutting e 0res.

n testimony whereof I aiiix my signature.

STANLEY PENKOSKI.
